WATER-HEATER Specification of Letters Patent.

Patented Dec. 29', 1914.

Application filed February 3, 1913,. Serial No. 745,915.

- Toall whom it may concern Be it known that I, PETER A. DnAsY, a citizen of the United. States, residing at Oakland, in the county of Alameda and State of "California, have invented certain new and useful Improvements-in. Water- Heaters, of which the following is a specifination. 1

This invention relates to water heaters,

and' one of the objects is to provide the heaterwith an improved type of coupling between the heating coil and the boiler, whereby circulation will be permitted.

Another object of the invention is to so construct this connection that the heating c'oil may be very readily disconnected from the boiler. v

v I Another object of the invention is to provide a novel construction whereby theprod 'ucts of combustion from the heating elements will be prevented from passing dipartially in elevationand partially in vertical section. Fig. 2 1s a sectlonal view through the coupling which connects the heating coil with the boiler. view similar to Fig. 1 showing a slightly modified form of boiler. Fig. 4 is a sectional view through the-coupling shown in Fig. 3. Fig. 5 is a fragmentary view of the flue which passes through the boiler.

Referring to Figs. 1, 2, and 5 it will be 'seen that this boiler comprises a casing 10 having the top 11 and bottom 12, thus forming the water chamber 13. This boiler is provided with the cold water inlet pipe 14 and with a hot .water draw-01f pipe 15,

which ispositioned adjacent the flue 16 located'to one side of the vertical center of the boiler. From an inspection of Fig. 5

a crimpe it will be eenthat the flue is provided with section 17, thus permitting the flue to expand and contract without any Fig. 3 is a' danger of straining the boiler and causing it to leak. It is, of course, obvious that when the products of combustion are passing through this fine that the flue will be heated to a greater extent than the top and bottom of the boiler and, therefore, if it were not for this crimped portion the boiler would be liable to be strained. A circulating pipe 18 is centrally located in the boiler and is held in place by a packing nut 19 in threaded engagement with the lower end portion of the pipe 18, and with a collar 20 formed I upon the bottom 12 of the boiler. A drip pan 21 is secured to the bottom of the boiler and 1s posltioned. beneath the'flue 16 so that Water formed from condensation in the flue will be caught and thus prevented from dripping. It is, of course, obvious .that when the heating element is in operation that this drip pan will beheated and the water in it thus evaporated: This boiler is provided with a lower portion 22 forming a heating chamber, and also forming a support for the boiler by having its upper porticn 23 reduced to form aneck about which the lower portion of the boiler fits'as clearly shown in Fig. 1. This heating chamber is supported by the usual floor-stand 24 and is provided with a door 25 to permit access to the interior of the heating chamber. A gas burner 26 is positioned in the heating chamber and is fed by a valve control gas pipe 27 having a pilot pipe 28 leading therefrom. This pipe 28 extends into the heating chamber above the burner 26,- thus permitting the burner to be easily lighted. From aninspection of Fig. 1 it will be readily seen that this burner is positioned out of alinement with the fine 16 and, therefore, theproducts of combustion will not pass directly out through the flue but must remain in the heating chamber for a short time before .passing out. Therefore, the

heating coil positioned in the heating cham-.

her will be heated more readily and, therefore, thewater will be very quickly heated. This heating coil 29 has one end threaded into the lower end of a coupling 30 and has extends up into thepipe 18 with'its upper end provided with a bushing 33 holding the pipe in the proper position and preventing; Water from passing downwardly through the pipe 18. Openings 3% are formed in the pipe 18 beneath thcbushing 33 so that the cold water in the lower portion of the boiler may pass through the opening 34; into the space surrounding the pipe 32 and through the arm 31 into the coil 29. This will then m pass through the coil where it is heated and y tably mounted upon a nipple 36 having its upper end portion threaded and screwed 20 into the packing nut 19.

From the above description it will be read ily. understood that the boiler :is filled by water enteringthrough thepipe 14; and that the waterin the boiler'passes through the openings 34 into the space surrounding the pipe 32 and then passes through the coil 29 and up through the pipe 32 into the pipe 18 from which it is emptied into the upper portion of the boiler. The hot water in the top 80 of the boiler can then be drawn out through the pipe 15. Iltshould be noted that this 'pipel5sis located near the flue 16 and that, therefore, the water which is drawn out will be keptvery hot since the products of com- 35 bustion pass therethrough thereby constitoting an additional means for heating the watenin theboiler. In. Figs. 3 and 4c there has been shown a slightly modified form of boiler. In this no form the casing 37 is mounted directly upon the floor support 38 and has its bottom 39 connected with a lining 40 having its lower edge portion secured to the casing, but having its remaining portion positioned in.

MS spaced relation 'to the casing, thus leaving a space 41 forming a water jacket. This boiler is provided with the water inlet pipe 42, the draw-0d pipe 43, and flue 4:4 similar to the construction shown in Fig. 1 and 60 is also provided with a drip pan 4:5. The

- burner 46 is similar in construction to the burner 29 and is fed by a valve control pipe 47 from which there leads a pilot pipe 48.

The heating coil 49 has its inlet end communicating with the lower portion of the water jacket and has its outlet end connected with the pipe 50 by the coupling shown in Fig. 4. This pipe 50 is held in place by a packing nut 51 in threaded engagcment with a collar 52 and communicates With'a nipple 53 having a threaded lower end portion so that the sleeve" 54 mounted upon the outlet end of the coil 49 may be connected with the nipple 53 by the 'union 55 .r'otatably mounted upon the sleeve afh'eating chamber .ipositioned beneath sai ing with said coupling whereby water ma.

54. in this form of boiler the water will. be very quickly heated since the outer jacket is comparatively narrow and, therefore the water will be partially heatcd'bc ore enterstheinlct end of the coil. In this form as Well as in thefo'rm shown in Fig. 1 the heutin coil can be very readily discluincctcd from the boiler since it is only necessary to unscrew the union 55 when it is desired to remove the coil. In connection with Fin. 1 it should be noted that the water onteri 5; the, coil will be partially heated since it passes into the narrow space between coupling 30 and pipe 32 will, thus be heated by the hot water in the pipe Si /sud fit? by the products of combustion in the-heatin chamber, i .7
